Sex & the Single Woman: Guilty?

Last night I was talking to one of my roommates about our other roommates’ boyfriends and I reiterated something I have said numerous times before: I am really lucky to have roommates who possess amazing guy judgement. One of my biggest fears is some jerk taking advantage of any of them, and I sleep much better at night knowing that they are dating guys who some of the best out there.

This leads me to wonder what I would do if one of them was dating a guy who was straight up bad news. I think it’s important to intervene, but where is the line? How do you make that judgment call?

All I can do is hope that they continue to make good choice. What do you think — how do you stop a good friend from making a bad mistake?
